Answer:

9.067cm

Step-by-step explanation:

x--- amount by which the length is reduced

area=(18-x)(15)=134

(18-x)=134/15

x=18-(134/15)

x= 9.067cm

Answer:

Angle AED = Angle CEB —> Opposite angles

So; Angle CEB = 95°

I hope I helped you^_^

∠AED and ∠CEB are opposite angles so they will be the same so ∠CEB will also 95°.

An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.

The identical endpoint of the two rays—known as the vertex—is referenced as an angle's sides.

Two opposite angles become by the intersection of two lines will always same.

Since E is the intersection point so ∠AED and ∠CEB are opposite angles.

So,

∠AED = ∠CEB

∠CEB = 95°.

Hence "∠AED and ∠CEB are opposite angles so they will be the same so ∠CEB will also be 95°".

Answer:

yes

Step-by-step explanation:

Answer:

The side lengths are:

15, 30, and 30

Step-by-step explanation:

Let x determine the length of the smallest side length then

the other one is said to be 15 in larger so it's x + 15

finally the third size is said to be twice as the smallest one so it's 2x

The perimeter is the sum of all three sides added up

x + 2x + x + 15 = 75 add like terms

4x + 15 = 75 subtract 15 from both sides

4x = 60 divide both sides by 4

x = 15

Answer:

i dont know

Step-by-step explanation:

Answer:

Step-by-step explanation:

5 units up means y is crease by y =>

y+5

and x unit left means x is decreasedby 3

=> x-3

thus new coordinates are (x-3,y+5)

Thus (x,y) → (x − 3, y + 5) (x, y) is

correct

Answer:

DAC=18(corresponding angles)

EAD= 162 degrees

Step-by-step explanation:

DAC=18(corresponding angles)

EAD=180-18(angles on a straight line)

EAD= 162 degrees

Answer:

Here, we have,

<HBA=18°

<DAC=?

<EAD=?

Now,

i)<DAC=<HBA=18°[being corresponding angle]

ii)<EAD+<DAC=180°[being straight angle]

or, <EAD+18°=180°

or, <EAD=180°-18°

or, <EAD=162°

Thus, <DAC=18° and<EAD=162°.

There are four parts of a circle, so you have to find out the area of the circle:-

10 cm=Radius

[tex]10^{2}[/tex]=100

[tex]\pi[/tex]=3.14

3.14*100=314 [tex]cm^{2}[/tex]

Now, find the area of the square box:-

Since half the side of the square is 10 cm, the total length of one side is 2*10 which is 20 cm.

Area=S*S

=20*20=400 [tex]cm^{2}[/tex]

Now subtract the area of the box from the area of the square:-

400-314= 86 [tex]cm^{2}[/tex]

That is the area of the shaded part.

Answer:

(-11 , -16)

Step-by-step explanation:

The midpoint will always be, as the term suggests, in the middle of the line segment. You simply need to find the distance for both x & y, and to apply that to the midpoint. In this case:

Endpoint (x₁ , y₁): (5 , 10)

Midpoint (x₂ , y₂): (-3 , -3)

Note that when finding distance, you will subtract the point₂ from point₁:

x: 5 - (-3) = 8

y: 10 - (-3) = 13

Therefore, each time you plot another point, you will be subtracting 8 from the x value, and 13 from the y value:

Endpoint (x₃ , y₃) = Midpoint (-3 , -3) + (_ - 8 , _ - 13) = (-11 , -16)

(-11 , -16) is your answer.

~

Using midpoint formula

[tex]\boxed{\sf (x,y)=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)}[/tex]

[tex]\\ \rm\longmapsto (-3,-3)=\left(\dfrac{5+x_2}{2},\dfrac{10+y_2}{2}\right)[/tex]

Firstly

[tex]\\ \rm\longmapsto \dfrac{5+x_2}{2}=-3[/tex]

[tex]\\ \rm\longmapsto 5+x_2=2(-3)=-6[/tex]

[tex]\\ \rm\longmapsto x_2=-6-5[/tex]

[tex]\\ \rm\longmapsto x_2=-11[/tex]

Now

.[tex]\\ \rm\longmapsto \dfrac{10+y_2}{2}=-3[/tex]

[tex]\\ \rm\longmapsto 10+y_2==2(-3)[/tex]

[tex]\\ \rm\longmapsto 10+y_2=-6[/tex]

[tex]\\ \rm\longmapsto y_2=-6-10[/tex]

[tex]\\ \rm\longmapsto y_2=-16[/tex]

Hence the coordinates are

Answer:

  (0, -3)

Step-by-step explanation:

The y-intercept is the point where the graph crosses the (vertical) y-axis. That point is halfway between grid lines marked -2 and -4, so is at the grid line with the value -3. The x-coordinate there is 0, so the y-intercept point is ...

  (x, y) = (0, -3)

_____

Since the y-intercept always has an x-coordinate of 0, we sometimes refer to the y-intercept using only the y-value: -3.

A percentage is a way to describe a part of a whole. The value of x is 5,000.

A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.

To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Given that 8.4% of x is 420. Therefore, we can write the given statement in the form of an equation as,

8.4% of x = 420

8.4% × x = 420

(8.4/100) × x = 420

x = (420 × 100)/8.4

x = 5,000

Hence, the value of x is 5,000.
